So the administrator login with username and password similar as OpenStack and use menu options it provide.

The guide using tool python virtualenv for creating environment. A recommend that if CLI and PraaS services are installed on same location so it's effective to use only one environment. Install virtualenv

auth_url = http://controller:5000/v3  #ip or hostname of controller
region_name = RegionOne

# config api url to PAT agent
[api]
# default PRaaS is installed on controller node because neutron server are installed on it
# if neutron l3-agent are installed on difference node, so change the url.
remove_pat = http://controller:3000/pat/remove
router_server_pat = http://controller:3000/router_server_pat
